What this MCCB does on a motor circuit
Its MicroLogic 2.2 M electronic trip unit provides three protection curves — L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous short-circuit) — plus selectable motor tripping classes 5, 10, and 20 so you can match the thermal memory to the start profile of your motor load.
Breaking capacity — what 200 kA Icu means at 415 V
For a motor branch feeding a large pump or compressor on a high-fault-capacity distribution board, that rating means the MCCB can interrupt a bolted fault without the upstream breaker needing to clear it — selectivity stays intact. The 200 kA figure at 415 V is the same across the 220 A frame, so you get full fault protection regardless of the trip unit rating.
Front connection both top and bottom, with a 35 mm connection pitch that matches standard busbar systems. IK07 impact rating handles incidental tool contact during commissioning. Five accessory slots give room for shunt trips, auxiliary contacts, or a motor mechanism without crowding the DIN rail below.
